Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed April 20, 1905. Serial No. 256,628-

Gates, of which the following is a specification.

This invention is a device for opening and closing sliding doors orgates, and has for its object to produce an improved device of the kindwhich may be operated at a distance from the dooras, for example, by aperson in a carriage or wagon.

In the accompanying drawings, wherein the invention is illustrated,Figure 1 is a perspective view. Fig. Qis a perspective detail of amodification.

Referring specifically to the drawings, 6 indicates a sliding doorcarried by hangers 7, which roll on a track 8. Extending perpendicularlyto the door is a lever 9, pivoted to swing vertically in the top of thepost 10. At the end nearest the door the lever is connected to ahook-block 11, Which has at the lower end oppositely-presented hooks 12.This block works under a strap 13, connected by bolts 14: at each end toa turning block 15, which turns on a central pivot held by brackets 16and 17. The block 15 has an arm 18, which projects up beside the doorand between two bolts 19, projecting from the side of the door. A plate20 connects the bolts and keeps the arm in place. The bracket 16 ispreferably located to form a guide for the bottom of the door, having abottom portion 16, over which the door slides, and an upturned portion16 at the back, which is fastened to the wall of the building.

The opening or closing of the door is effected by rocking the block 15.The pins 14 are so located that one of them will be engaged by one ofthe hooks 12 when the hook-block is lifted, and this engagement turnsthe block 15 and swings the arm 18, Which carries with it the door, toopen or close the same, the hookblock 11 being lifted by the pressure onthe outer end of the lever 9.

In the modification shown in Fig. 2 two separate hooks 12 are used, eachof which is operated bya lever 9 the other parts being the same. Onehook catches the pin 14 on one side, and the other book catches the pinon the other side, and it swings the arm accordingly to either open orclose the door.

The side edges ll of the hook-block 11 are so shaped that by contactwith the upper pin 14 the block is shoved over, so that the hook on theopposite side Will go to the other pin.

What I claim-as new, and desire to secure by Letters Patent, is-

1. An opener for sliding doors or gates, comprising a rocker havingaprojecting arm connected to the door or gate and a pair of projectingpins on opposite sides of its pivot, a hook-block having hooks onopposite sides thereof, working between the pins and arranged to engageone or the other, and a lever connected to said block, to lift the same.

2. An opener for sliding doors or gates comprising a rocker having anupwardly-projecting arm connected to the door or gate, and alaterally-extending pin, and a lever having a hook arranged to engagethe pin and turn the rocker.

3. An opener for sliding doors or gates comprising a pivoted rockerhaving an upwardlyextending arm. loosely connected to the door or gate,and also having a pair of pins pro jecting on opposite sides of thepivot, a block movable up and down between the pins and opposite hooksat its lower end and cam edges between the pins adapted to swing theblock to one side or the other by contact with the pins, and anoperating-lever connected to the block.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing Witnesses.
